THEIR ZIT TD1-z NEM Patented Sept. 24, 1929 UNITED-,STATES PATENT oFFicE CARL A. BROWN AND-REAS C.` NIELSEN, OF CLEVELAND, OHIO, ASSIGNORS TO GENERAL ELECTRIC COMPANY, A CORPORATION OF NEW YORK GAS BURNER Application filed July 23,

.Our invention relates to gas burners' and is adapted for use with natural or artificial gas. The object of our invention is to prov Vide a burner from whichy a uniform intense heat is secured. We secure this result by providing means for securing a very thorough mixture of the gas with air and for securingv a very uniform pressure. Our invention is adapted to glass'working, particularly to the '10 various operations on bulbs and tubing entering into the manufacture of incandescent lamps and similar devices. Further advantages and features of our invention will appear from the description which follows of 15 species thereof and from the accompanying drawing in which Fig. 1 is a front elevation partially broken away; Fig. 2 is a horizontal section; Fig. 3 is a side elevation partially broken away and in section; Fig. 4 is a partial 20 perspective of the fire plate; and Fig. 5 is a partialfrontelevation of a modification of the burner adapted for artificial gas.

Iny the drawing isa casing or burner body within. which is located a distributing chamber lor inner tube 11 which rests on a shoulder formed at the -'junction of the casing 10 with a bottom chamber 12 to which is connected the intake pipe 13. The casing 10- may have an extension 10 by means of which the burner may be adjustably supported. The tube 11 has, along the rear thereof, distributing orifices 14 which are preferably arranged in a double row and staggered and communicate with the outer distributing chamber 15 formedl between the inner tube andthe casing 10. Diametrically opposite to the. rows of orifices 14, the casing 10 has an external slot 16 extending substantially its entire length and communicating therewith are larger high pressure orifices 17, preferably arranged in a double row and staggered, and on each side of said double row is a row of smaller low pressure orifices 18, the latter also being staggered. A fire plate 19 is mounted in said slot and is T-shaped in horizontal section. It contains a double row of staggered high pressure fire orifices 20 which are aligne-d with orifices 17. The fireplate forms with the bottom of slot 16 a pair of lateral low pressure distributing chambers 21 with 1923. Serial No. 653,084.

A burner of the above described construction alone may be used to advantage for artificial gas. However for natural gas it hasV been found desirable to provide a means for further breaking up the current of gas issuing from the slots 22.' Members such as strips of wire gauze 23 having numer ous small apertures therethrough andarranged so that each strip covers a row of slots 22 have been found to be particularly serviceable for this purpose. These are removably held by plates 24 and bent so as to cover the said slots.

VIn operation gas and air in proper proportions and suitable pressure enter chamber 12 and fill tube 11. The mixture then flows through double row orifices 14 into the outer distributing chamber 15. The mixture issuing from the orifices 14 strikesagainst thev wall of the casing 10 and is deflected around the chamber 15 and out through high pressure orifices 17 and low pressure orifices 18. This arrangement insures a uniformity of pressure in the gas mixture issuing from tlie'several orifices. It also serves thoroughness of mixture of t ents. The result is that a more uniform heat to improve the he gas constituis secured than from burners otherwise vconstructed. The low pressure from the mixture flowing flame produced from the slots serves'to prevent the blowing out of the high pressure flame.

The ,slot construction is particularly effective since it enables the low pressure flame to be brought very close to the high pressure orifice.

4The provision of the supplementary means, specificallythe gauze covering, for breaking up the sure orifices permits the Heret-ofore considerable as mixture issuing from the low presof natural gas.

difficulty has been tions on glass tubing which e descent lamp manufacture.

nter into incan- Our invention overcomes this difficulty. The auze being spaced from the orifice causes t e flame to form between the gauze and the orifice which spreads out and this is particularly effective in maintaining the main fire.

What we claim as new and desire to secure by Letters Patent of the United States, is:

1. A as burner comprising a casing, an inner tu e spaced from said casing to form a chamber, said tube having orifices on one side thereof communicating with said chamberand said casing having longitudinal rows of orifices disposed on the side thereof opposite to that of said inner tube orifices, and a fireplate having a body portion provided with a row of orifices communicating with a row of those 1n said casing and a wlng portlon spaced from said casing opposlte a row of said casing orifices to form a distributing chamber and having a row of orifices therein each disposed adjacent to one of the said body portion orices. l

2. A gas burner comprising a casing, an inner tube spaced from said casing to form a chamber, said tube having orifices on one side thereof communicating with said chamber and said casing having longitudinal rows of orifices disposed on the side thereof opposite to that of said inner tube orifices, and a fireplate having a body portion provided with a row of orifices communicating with a row of those in said casing and a wing portion spaced from said casing opposite a row of said casing orifices to form a distributing chamber and having a row of slot-shaped orifices therein each disposed adjacent to one of the said body portion orifices.

3. A gas burner comprising a casing, an inner tube s aced from said casing to form a chamber, said tube having orifices on one side thereof communicating with said chamber' and said casing having longitudinal rows of orifices disposed on the side thereof opposite to that of said inner tube orifices, and a fireplate having a body portion provided with a row or orifices communicating with a row of those in said casing and wing portions each spaced from said casing opposite a row of said casing orifices to form a distributing chamber and having a row of orifices therein Aeach disposed adjacent to one of the said body portion orifices. i

In witness whereof, we have hereunto set our hands this 19th day of July, 1923. CARL A. BROWN.
